By pulling the inner side of the loop, the adjacent spring 8 I compressed' as they pass thefiange l9 and f In Figures 8 and 9" we have shown a modirp fication in which the flexible handle is replaced by a handle 21 of rigid material, such as wire, pivoted to the forward end of the strip 7-by a hinge member 22. The normal position of the handle will be as" shown in full lines in Figure ;8.f Whenitis desired to remove the filler, the handle is forced into the positionshownf in dotted lines lin this figure. The handle will act as a lever cooperatingwith the edge of the flange as a fulcrum to force the strip beyond the flange so "that the tiller may be withdrawn.

InFigures 5, 6 andiYIwe have shown a tmodificationjin which thefform of thefilleri is-slightly changed and in which the filler is connected by a 'guardmember for holding downthe packing at the frontend of the axle. In this modification curved "metal I platesQl are used in'place of thei fiber strips 7 to contact withthe-bearing'surfaceof. the
